What is Next.js?
Key Features of Next.js
Setting up Next.js is relatively straightforward since it has its own Node.js server. This allows developers to use the framework to deliver users simple indexable HTML results without the complexities of programming architecture, data caching, and more.
Next.js also provides web developers with all the necessary features for developing professional and reliable web solutions:
Ensures high SEO performance by performing server-side rendering.
Comes with a Head component that allows for setting dynamic meta-tags.
Automatically code-splits, ensuring fast page loading.
Has a wide IT community support, making it easier to find specialists ready to help with project issues.
Use Cases for Next.js
Interactive user interfaces
Dynamic web apps
Static applications, and more.
Comparing NestJS and Next.js
To get a full picture of the Next.js vs NestJS comparison, let's compare these two frameworks based on several key characteristics.
Architecture and Development Approach
Comparing the approaches to backend and frontend development on both platforms, we have the following results:
Language: Primarily TypeScript, providing type-checking to verify code components during compilation, simplifying the work of programmers.
Architecture: Modular structure that helps create microservices apps with tools for handling HTTP requests, databases, and API connections to implement business logic.
Server Logic: A set of functions, including middleware, security tools, and decorators, to handle various aspects of request processing.
Data Handling: Uses various databases, such as MongoDB and Object-Relational Mapping (ORM) systems, including TypeORM, Sequelize, and Prisma.
Architecture: Server-side rendering (SSR) and static site generation (SSG) improve productivity and page loading speed, positively impacting SEO performance.
API Routes: Simple internal functionality and handling various types of requests without setting up a separate internal server.
Data Handling: Data retrieval through functions like getServerSideProps, getStaticProps, and getInitialProps allows developers to fetch data on the server-side during rendering.
Server-Side Rendering vs. Client-Side Rendering
NestJS is not designed for client-side rendering (CSR). However, the framework can serve static resources and provide API connections for external apps built on Angular, React, or Vue.js platforms. NestJS also allows the creation of websockets for interactive two-way communication between the server and the client.
Next.js defaults to server-side rendering but is also oriented towards CSR, which is typical for React applications. It provides features such as automatic code splitting, pre-fetching, and optimized rendering for fast and responsive user interaction.
Scalability and Performance Considerations
These characteristics are important aspects of creating a successful web application, and both NestJS and Next.js provide all the necessary features and capabilities.
Building websites with NestJS guarantees easy horizontal scalability. The framework also supports microservices architecture, which breaks down web solutions into multiple manageable services that distribute the load and enhance scalability.
Apps developed on Next.js are horizontally scalable. The platform also supports serverless deployment, enabling web solutions to automatically scale as traffic increases.
Characterized by high speed and efficiency thanks to Node.js. Its unmanaged architecture allows for handling a large number of connections simultaneously. NestJS also provides various query optimization methods, caching mechanisms, and more.
Both frameworks use similar methods to enhance scalability and improve performance: database query optimization, caching, and serverless deployment. Thus, NestJS and Next.js provide you with ample opportunities to achieve easy expansion and increased capacity for your web resource.
Choosing the Right Framework
To make the right choice of a development platform, consider the following recommendations from experienced experts at Lampa:
Project Requirements and Goals
Begin by researching the idea behind your project to determine:
Key features and their quantity.
The complexity of the solution.
The need for scalability and performance.
After conducting research, you will understand which framework best suits your project. Using this data, you will also find it easier to assemble an IT team with the expertise and tech stack that precisely matches your project's needs.
Combination of NestJS and Next.js
Developers often use the strengths of Next.js and NestJS to create different parts of full-featured applications. For example, Next.js, by default, separates API routes to simplify deployment in a serverless environment, which can lead to a high number of database connections.
NestJS can support proxy API routes with a database or the Mongoose library, which establishes connections between MongoDB and your runtime environment. This simplifies combining sets of connections and optimizes your site's performance.
The server-side part developed with NestJS helps address data access issues, while Next.js focuses on the user interface level. This results in a more stable and reliable operation of your web application.
In summarizing the competition of Next.js vs. NestJS, we see that these frameworks are different technologies, each designed to achieve specific goals:
NestJS is a reliable environment for building scalable and easy-to-maintain server-side applications.
Next.js, on the other hand, is applied in front-end development and offers all the necessary features for creating static websites.
Therefore, when choosing a suitable framework, consider the type of your project and what you need to build – back or front-end.
